4X4, 6X6 AND 8X8 CHASSIS LAYOUT FOR ALL TRUCKS ... [BETTER]
All Category 1 (and follow-on series) share a modular design. They have a torsionally rigid box-section chassis frame with rigid hub-reduction axles sprung by coil springs and shock-absorbers. The engine is mounted inside the forward-control cab, which is separated into a driver and engine compartment by a firewall. The engine is located to the rear of the driver compartment instead of beneath it, this enabling total height to be kept below 2.9 m, which means the trucks can be transported on standard railway flatcars. The characteristic, cut-away corners of the otherwise box-shaped cab ensure compliance with the railway loading gauge. The cab of early production examples does not tilt forward for maintenance because the vehicles were still based on the amphibious prototypes. The tilting cab was only introduced in the mid-80s.
4X4, 6X6 AND 8X8 CHASSIS LAYOUT FOR ALL TRUCKS ...
The primary structural feature of Tatra trucks is the central load carrying tube, also called a backbone frame. All other parts of the truck are mounted to this rigid assembly. The inherently high torsional and flexural rigidity of this layout protects superstructures from the motions and forces on the axles. Torque distribution to the axles is also carried within the backbone.
Many different types of military trucks were developed and produced between the wars but in 1942, when the TATRA company was under German war industry supervision, a special 6x6 truck was developed, whose task was to operate in the most difficult terrain covered with snow and under temperatures deep below freezing point. For this purpose the TATRA-concept chassis with its rigid backbone tube and independent swing half-axles, as well as the air-cooled V 12 engine were further developed. The vehicle, designated as TATRA T-111, was never used in WW II but for its outstanding performance and driving qualities it formed a basis for later exports of commercial off-road TATRA trucks to the USSR in the late 40's and early 50's. TATRA T-111 was also used as a standard military truck for the Czechoslovak Army and many other armies of the former Warsaw Pact.
More than 8,700 units of TATRA T- 815 family military trucks and various types of chassis (4x4, 6x6, 8x8) were delivered to the Czechoslovak and, later on, Czech Army, as well as to many armies worldwide.
Knowledge and experience from the KaMAZ-4310 family has been incorporated into the newer Mustang series. The Mustang series comes in a 4x4, 6x6 and 8x8 variant, called the KaMAZ-4350, -5350 and -6350 respectively. All versions feature the same forward control cab and basic chassis design. A wide variety of body types can be installed. Normally a flatbed with drop sides and tarpaulin cover is fitted. The Mustang series features an unarmored driver's cab. An add on armor kit for the cabin is optional.
This unified range consisted of three basic models - N4510 (4x4), N4520 (the 6x6) and N4540 (8x8) with the payload 5, 7 and 10 tons. The trucks have a modular design with a spar frame and a standardized rectangular all-metal 3-place cabin on a folding aluminum frame with a hatch in the roof, a metal flatbed body with aluminum ramps, removable benches and an awning, wide-single wheels. In the rear side of the cabin was located a 12.8-liter diesel engine Deutz F8L413F V8 air-cooled, 256 hp for the 4x4 variant, and 320 hp (with turbocharger) for other versions. All vehicles were equipped with hydraulic mechanical 6-speed gearboxes ZF, 2-speed transfer gear-boxes with a built-in differential, planetary reduction gears, double-circuit hydraulic brakes, spring suspension with hydraulic shock absorbers and lockable differentials. The models N4610 (4x4), N4620 (6x6) and N4540 (8x8) were equipped with the winches Rotzler with a pulling force 5.0-7.5 ton-force, the models N4530 and N4550 (6x6) with a power takeoff shafts were used for assembling various bodies and engineering machinery, the N4640 (8x8) with 1-ton hydro crane is used to work with changeable bodies. Some trucks received longer cabins with two sleeping places over the engine. All versions have the total mass of 14.5-24.2 t, maximum speed of 90 km/h and could tow 5-10 t trailers. The N4540 chassis was used for assembling straddle carrier bodies, bridges launchers, radar stations and anti-aircraft missile systems Roland-2. Totally 8385 cars of this range had been produced from 1976 to 1985. - N4510/N4520/N4540 - basic chassis 4x4/6x6/8x8.- N4610/N4620/N4540 - chassis 4x4/6x6/8x8 with Rotzler winch.- N4530/N4550 - 6x6 chassis with a power takeoff shaft.- N4640 - 8x8 chassis with hydro crane.
The company produced the first Czech car, the Präsident in 1897. And a year later came its first truck. Serial production of trucks started in 1915 with 105 TL-2 vehicles. The mass production of trucks started in the middle of the 1920s, during the era of the first Czechoslovak republic (1918-1938). In 1923 a chassis consisting of a central load-carrying tube, at the end of which a directly air-cooled engine and transmission were installed with independently mounted swinging half-axles, was introduced as a new product, and marked what was called the Tatra concept. A six-wheeler model T72 was the first one largely used by the army as cargo and personnel transport. It was also manufactured under license in France, followed by T82, 92 and 93 built for the Romanian army, already under the nazi occupation regime (1939-1945). After 1945 Tatra was established as a state-owned company.
In 1967 came the first four-axle design, the T813 8x8 Kolos platform, with modular construction technology. T815 was introduced in 1982, with simplified construction and more powerful engine, using the traditional tatra concept of rigid backbone tube and swinging half-axles giving independent suspension. The vehicle, designed for extremet off-road conditions, exists in all imaginable chassis configurations: 4x4, 6x6, 8x8, 10x8, 10x10, 12x8 and 12x12. Many were and are still produced in military variants from simple 4x4 troop transport to the 12x12 BrahMos supersonic cruise missile carrier of the Indian army. It was completed in 2008 by the T810 model, a medium truck at 4x4 or 6x6. 041b061a72
